Hi, Not sure where to post this question, but here it goes for anyone willing to help. I just bought a WD Slim Passport drive, with much online chat about it being very simple to re-format for use with Mac. I am having some trouble with the very first step in Disk Utility. I am to select the disk on the left pane, and then select Erase from the top menu. THEN select Window NT File System (NTFS) from the Format drop down. Finally click on Erase. Well, the Format drop down shows the NTFS grayed out, of course along with a grayed out Erase button. I have tried looking up ways around this using Terminal, but Terminal doesn't sen to recognize the drive at all. Any instruction on how to properly re-format a windows drive for Mac would be GREATLY appreciated! THANK YOU!
